Description

A kind of air ventilation reflective safety helmet

Technical field

The utility model field relates to three parts, and Part I is to utilize material self-characteristic to make safety cap have good permeability, and Part II is to organize air-flow, makes the inside and outside portion of safety cap air form hot pressing poor, realizes safety cap gravity-flow ventilation.Part III is the character of utilizing fluorescent material reflect visible light at night, realizes the reflecting at night of safety cap with visible.

background technology

Along with urbanization acceleration and infrastructure construction investment continues to strengthen, the building industry of China, is just entering gold developing period, and by 2015, the construction market of China will become maximum in the world construction market.First constructions work will guarantee workmen's safety and health at work, and this is a prerequisite the most basic, is also the embodiment of social civilization level.But the complicated difficult of construction environment is to meet the demands.In recent years, the security incident in construction occurs repeatedly, and because operating personnel does not have enough safety prevention measures, causes many unnecessary injures and deaths.Security protection articles for use are the necessary preventative equipments of protection labourer's safety and health in labout process, are the important measures that prevent or reduce industrial accident, prevention occupational disease.

Existing safety cap has obtained very well improving and developing in safety coefficient, but function singleness can not provide comfortable environment for use to the safety cap personnel of wearing.Because project process time requirement is urgent, carry on construction work at night and often carry out, due to the environmental condition effects limit that carries on construction work at night, cause knowing identification workmen's position, cause potential safety hazard.

Chinese patent application discloses a kind of novel ventilated safety cap for No. 97235027.6, it is characterized by: a cap shell and a ventilative inner cover, and on cap shell and inner cover, open respectively general mood hole.The ventilation effect of this safety cap is good, but the cap shell of this safety cap and inner cover structure manufacture craft are more complicated, has changed the structure of safety cap.Chinese patent application discloses a kind of fluorescent safety helmet No. 02269759.4, it is characterized by: in cap housing, and injection moulding fluorescent grain.When this safety cap is conducive to carry on construction work at night, operating personnel distinguishes below workmen's position aloft.But this safety cap has changed the structure of safety cap itself, and manufacture craft is more complicated; And fluorescent grain has chemical property, once damage, be unfavorable for environmental protection, long-term production is used and is unfavorable for the energy that economizes on resources.

Summary of the invention

The purpose of this utility model is to provide one and utilizes material behavior realization ventilative, utilizes internal heat air property to realize gravity-flow ventilation, utilizes fluorescent material character to realize noctilucent safety cap.

Thinking of the present invention is: use TPEE material to replace traditional material to make safety cap, this material good permeability, is conducive to the inner heat exchange of safety cap, and its moisture-penetrable ventilated ability can reach 0.1 m2Pa/W, there is good mechanical property, can meet the requirement of strength of safety cap.In the perforate of the safety cap left and right sides, and opening symmetrical hole at safety cap top, is little according to hot-air density, the character that can float, and organization security cap inner air flows, and makes it reach the effect of gravity-flow ventilation.Its Natural Ventilation Principle is: when safety cap inner air is heated, density reduces, and can float.According to " stack effect " principle, open pore below safety cap, introduces outside Cryogenic air, organizes air-flow, and safety cap internal high temperature air is got rid of by the perforate of safety cap top, realizes nature cooling.The reflective of safety cap realized by within one week, pasting luminous patch around safety cap surface.Luminous patch low price, can cut into various moulding as requested, has good hot pressing to scald sticking effect, and water-wash resistance is good, and when light-illuminating, glistening intensity is high, and this product is placed in to dark place, has extremely significant luminous effect.This material is sticked on to safety cap surface, and workman is when night work, and in construction site, light impinges upon on safety cap and can send light, and convenient construction Field Force management, is also conducive to ensure workmen's life security.

The technical solution used in the present invention is: a kind of air ventilation reflective safety helmet.It is characterized in that this safety cap: use gas permeable material to be manufactured with and be beneficial to heat extraction hydrofuge; In side and top drilling, be conducive to organize air-flow, at the brim of a hat place, one week sticking reflecting material noctilucence can be recognized.

Advantage of the present invention: this safety cap has adopted new material, has strengthened the permeability of safety cap, is conducive to the heat radiation of safety cap self.By pore is set, realized the air current composition of safety cap inside, utilize the physical attribute of safety cap internal heat air to realize the gravity-flow ventilation of safety cap.At outer surface, paste fluorescent material, make the safety cap can identification at night.The not a large amount of original structures of safety cap that change of above technical measures, can not produce a very large impact the mechanical property of safety cap in sum.All materials and technical measures are all simple, convenient, easy to implement and income is large, have good exploitativeness, practicality, feasibility and environmental protection and energy saving.

Accompanying drawing explanation

This Figure of description comprises that following three width figure: Fig. 1 are the ventilative schematic diagrams of TPEE material, Fig. 2 is an air ventilation reflective safety helmet left side (right side) side view, this figure has reflected side, a safety cap left side (right side), the arrangement of the arrangement mode of square ventilation hole (2) and reflectorized material (3).Fig. 3 is the top view of air ventilation reflective safety helmet, and this figure has reflected the arrangement mode of the square ventilation hole in safety cap top (2).

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail. as Fig. 1, TPEE (1) material use absorption " absorption-diffusion-desorb " principle, macromolecular material is carried out to specific hydrophilicity-imparting treatment, be allowed to condition under uniform temperature and moist gradient, the gas molecules such as steam and hydrophilic radical are with hydrogen bond and other molecular separating force effects, in the high side adsorbed water molecule of humidity, by the hydrophilic radical on macromolecular chain, be delivered to the side desorb that humidity is low, the principle of its waterproof

Be certainly in the continuity of material self and larger film tensile strength, this material is made safety cap all the time can increase the gas permeability of safety cap self.

As Fig. 2, in the safety cap left and right sides, apart from the brim of a hat 100mm At The Height, open respectively 4 rectangular ventilation holes holes (2), bore hole size is 50mm × 30mm, hole spacing is 50mm.8 holes of the left and right sides are air admission holes, for introducing the air of safety cap outside, organize air-flow.Around apart from helmet brim 300mm At The Height, the reflectorized material (3) that to paste width be 100mm.Reflectorized material (3) is according to microprism principle of reflection, can indirect illumination light at night, send light, and the construction operation personnel of safe wearing cap are more easily identified, reduce the dangerous possibility occurring.

As Fig. 3, at safety cap top, be arranged symmetrically with 4 rectangle holes (2), bore hole size is 50mm × 30mm, hole spacing is 50mm.These 8 holes are steam vents, and because safety cap inner air is heated through the mode of radiation heat transfer by head and extraneous heat, temperature raises, and density reduces, and after inner air is heated, can rise.By these 8 pores, can get rid of safety cap internal heat air, play cooling-down effect.
